Definitions

  • the present invention relates to a portable drill as well as a removable handle therefor.
  • the object of the present invention is to allow the user of such a drill to control the position of the working axis thereof, whether this position has to be horizontal, vertical or inclined.
  • the drawing represents, by way of example, an embodiment of the object of the invention and a variant.
  • Fig. 1 is a plan view of a portable electric drill.
  • Fig. 2 is a plan view of the side handle of the drill shown in FIG. 1, on a larger scale.
  • Fig. 3 is a section along line III-III of FIG. 2.
  • Fig. 4 is an end view of the handle shown in FIGS. 2 and 3, and
  • Fig. 5 is a section through a detail of a variant handle on a larger scale than that of FIGS. 2 to 4.
  • the portable electric drill shown in fig. 1, generally designated by 1, has, extending the front end of its housing, a cylindrical sleeve 2, traversed by the spindle of the machine carrying the drill bit tightening mandrel, designated by 3.
  • a collar 4, split in 5, and which can be tightened using a wing screw 6 on the sleeve 2, is provided with a cylindrical handle 7 allowing the operator to hold the drill with one hand while the another is engaged in the rear, annular handle of the machine, not visible in the drawing.
  • the handle 7 carries, housed in a radial clearance 8 which it presents for this purpose, a bubble water level 9, circular, allowing, when it is turned upwards, to check that the drill 1 is held in the desired position.
  • the handle 7 is rotatably mounted on the collar 4 using a rod 10, permanently screwed into the collar, the outer end of which, designated by 10a, is threaded and carries a blocking chicken 11 allowing, when it is unscrewed, to release the handle 7, which can then be turned on itself relative to the collar 4, or on the contrary to block it in position on the necklace.
  • the handle 7 has a part 7a forming a collar, provided with projections 7b forming an annular graduation moving, during the rotation of the handle, opposite an index 12 which has the upper face of the collar 4.
  • the user can, for any desired position of the drill, check whether it is held correctly.
  • the correct position of the bubble at the center of the water level 9 indicates that the axis of the drill is in a horizontal plane.
  • the position of the vertical plane, in which the axis of the drill must be located it is easily verifiable by the operator since he is able to observe the drill from above.
  • the handle 7 is then rotated 90 ° relative to the position shown in fig. 1, so that the spirit level 9 is turned upwards when the drill is in the position of use.
  • the correct position of the level 9 bubble then allows the operator to ensure that the axis of the drill is perfectly vertical.
  • the variant of fig. 5 differs from the first embodiment in that the collar, designated by 13, on which the handle is mounted, designated by 14, carries a stop finger 15 parallel to the longitudinal axis of the handle, s' engaging in a clearance 16, formed in the end of the handle, which prevents the latter from turning on itself.
  • a bubble water level 17 is carried by a ring 18 rotatably mounted on the handle 14, which a knurling 19 makes it easy to grasp to make it rotate.
  • a jumper device comprising a ball 20 subjected to the action of a return spring 21, carried by the frame 13 of the handle, cooperates with one or other of the recesses 22, only one of which is visible in the drawing , to determine the different angular positions that the ring 18 can occupy on the handle 14.
